If you did take a journal...
And if one of your bunk-mates should happen to read it, and they make higher levels before you, the staff will find out.
That's how the game is played in WWASP programs. Let's say Johnny has been in a lower level cabin for 12 months, working his way up to level 3 and staying there for a while, finally he makes it to level 4. Upper levels! Well good for Johnny, but bad for Johnny's old friends still back in the cabin.
Johnny now lives with Jr. Staff, who have much easier rules and get more privelages than the lower levels. They get just enough more treats than lower levels to keep them happy, and defensive about being 'dropped' back to lower levels for any rule violations.
The upper levels will convince Johnny, especially at seminars, if he doesn't spill the beans on what he knows, EVERYTHING he knows, he will be dropped. Accidentely tell Johnny (your best? friend) a secret? oops, big mistake! Or maybe I get up to the higher levels first and he uses the notebook thing against me in order to drop me back down, and possibly raise himself.
This is what life is like in a program. 24/7 emotional stress, knowing at any moment, for ANY reason you could be dropped to where you started. That's the equivilent to losing a year, two, or more of your life. For ANY REASON.
Unless you are wise [or shy] enough to not talk to anybody, you never quite know what everyone else knows about you.
It sucks.
